Yeah but you're doing that unencumbered, with modern shoes and on paved roads.

When people say it's bad to turn off the computer via the power button, they're not talking about tapping the button and letting windows go through the shutdown process. Instead, they mean the act of pressing and holding the power button to turn the PC off, which cuts the power to the computer and turns it off suddenly.

If the power to the computer is cut suddenly, files may become corrupted. If your computer was in the middle of writing information to the hard drive, this may cause that information to not be stored correctly, meaning some programs may not work properly in the future.

Also, many older computers didn't tell windows to shut down when the power button was pressed. On an older computer, pressing the power button just immediately shuts the power off.

A consulting company or professional services firm basically 'rents out' their employees to other companies that may need help with a specific task (1) or can't do a task on their own for legal/business reasons (2).

1. Sometimes, a company just needs a specialist to help them achieve their goals with a specific project. Maybe they need the services of an appraiser, or an actuary, or a PR person, or a software developer, or a lawyer with a specific specialty, for a limited time. So, this company asks a consulting firm to 'borrow' someone with the specific skills they need.

2. Consulting agents are often hired by companies to do audits. A company can't really audit itself effectively, since everyone in the company has a vested interest in making themselves look good. Bringing in an auditor from outside allows a more neutral look into how a company is running. This is especially important if the results of the audit will be shared outside the company that requested the audit to be performed.

It's not true though.

Wires used to be made (maybe still are?) by heating up metal and stretching it over and over.

The more times it was stretched, the thinner it got. They used dies for this (to shape the wire). The wire was pulled through a set number of dies to get a set size. To get a thin wire, one had to pull the metal through a larger number of dies. Hence the number going up as the wires get thinner.

A lot of the "every day" jobs like translator, data analyst, etc. can be applied to directly. The government (in the US at least) even has websites for this:

They also sponsor events to look for talent sometimes, like the "NSA Codebreaker Challenge" which tests IT and programming skills. The winners of these challenges may be recruited.

There are a few reasons, but it mainly comes down to increased efficiencies at mixing air and fuel.

Older engines had carburetors. These were mechanical devices that mixed air and fuel for the engine to burn. Carburetors were not nearly as efficient as fuel injection, which is the technology cars use today. Fuel injection gets a near-perfect air-to-fuel ratio delivered into the engine.

Older cars had pushrods for their air intake and air exhaust systems. Modern cars have overhead cams with Variable Valve Timing (VVT). The way old cars let air into their engines was completely static - now, cars can control how much air the send into the engine and change the amount of air sent into the engine at different engine speeds to create more efficient fuel burning.

Due to advances in manufacturing, engines now also have higher compression and can withstand higher speeds.

Finally, in regards to the 70s specifically, environmental legislation that came in at that time caused some American manufacturers to detune existing engines (made before the environmental regulations) and make them weak from the factory to meet emissions requirements, instead of designing new engines right away.

I'm guessing the documentaries don't dwell on those speeches for a long time, right?

It's hard to show just one excerpt from a speech that is potentially an hour-or-so long without context. The speeches need to be summarized because you wouldn't be able to glean what they're talking about just from listening to a few minutes.

Here's Hitler's speech about Stalingrad:

https://en.wikisource.org/wiki/Adolf_Hitler%27s_Stalingrad_Speech

You'll see it's kind of all-over-the-place and choosing just a few lines from it to summarize is hard. In this speech, he talks about his own life, his coming to power, he compares bolshevism to communism in Wiemar Germany, he talks about previous German military successes, and so on. Picking a few lines from this speech to summarize it is very hard.
